CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of U.S. ProvisionalPatent Application No. 62/214,803 filed on Sep. 4, 2015 and titled“Wearable To Monitor Exposure To UV Radiation,” the disclosure of whichis incorporated herein by reference in its entirety for all purposes.

TECHNICAL FIELD

The subject matter described herein relates to a wearable device and inparticular to a wearable device that can monitor a wearers exposure toultraviolet (UV) radiation.

BACKGROUND

Overexposure to UVA and UVB rays from the sun can cause many problemssuch as wrinkling, premature aging, sunspots, and even the deadliestform of skin cancer, Melanoma. Many people are unaware of when they havebecome overexposed.

Clothing does not prevent UV rays from reaching the skin and causingdamage. A white shirt has the SPF of about 7, when wet the protectionoffered drops to about 3. One way to detect if a piece of clothing fullyprotects a person is holding it up to the sun, if any light goes throughit can still be harmful. Any person, especially a child, is susceptibleto the damage of the sun's UV rays. 10% of the work force in the UnitedStates work outdoors.

People that spend time on the beach need to be extra careful of theirexposure to the sun's UV radiation. Even when in shade, sand can reflectroughly 17% of the sun's UV rays. Also, even when living in areas wherethere is relatively little Sunlight, the UV rays can still damage skinyear-round. UVB rays cause sunburn and are the most noticeable, but bothUVA and UVB rays can penetrate through clouds, so even on a cloudy daythe sun can be very harmful to the skin. Furthermore, residing orspending time in areas with snow, it is a common necessity to usebroad-spectrum sunscreen because snow reflects roughly 80% of the sun'sUV. Reflected UV rays have a cumulative effect on the damage afforded toa person.

UVA rays can be harmful even indoors. UVA rays penetrate through glassallowing them to be harmful even when indoors. In limited quantities,UVB rays can be beneficial to life, for example in the intake of VitaminD, however overexposure can be very harmful to humans, especially as theozone layer gets more depleted more UVB rays penetrate and reach groundlevel and create greater harm.

People have limited knowledge or sense of their exposure to UVA and UVBrays. The ever-changing weather patterns, the constant moving fromshade, to sunny areas, and time spent indoors compared to outdoors, makedetermining one's exposure to UVA and UVB rays almost impossible.
